Struct polkadot_sdk_frame::traits::WrapperKeepOpaque

pub struct WrapperKeepOpaque<T> { /* private fields */ }

Expand description

A wrapper for any type T which implement encode/decode in a way compatible with Vec<u8>.

This type is similar to WrapperOpaque, but it differs in the way it stores the type T. While WrapperOpaque stores the decoded type, the WrapperKeepOpaque stores the type only in its opaque format, aka as a Vec<u8>. To access the real type T Self::try_decode needs to be used.

Implementations§
